Brain imaging in prehospitally treated stroke patients

<p>. Patient with ischemic stroke: Prehospital CT excluded contraindications for thrombolysis as a precondition for prehospital rt-PA thrombolysis (A). The “hyperdense middle cerebral artery” sign (arrow) suggested middle cerebral artery occlusion that was later confirmed in hospital by angiography (B), and reopened by intraarterial recanaliziation (C). Diffusion-weighted magnetic resonance imaging at day 7 showed the residual infarction (D). Patient with hemorrhagic stroke: Prehospital CT scan allowed immediate diagnosis of intracerebral hemorrhage with ventricular extension (E), as a precondition for prehospital differential blood pressure management and telemedicine consultation with hospital experts. CT performed at day 24 shows the residual lesion (F).</p
